Had a Jasper transmission put in my GMC Yukon XL2005. came with a great backing but 1 year into the use of it. it went bad so they fixed for free. another year and a half the same problem happens but this time since it is 6 months out of warranty they said more or less to take a walk. I find this very disturbing that they wouldn’t offer to do something for me? O yes they did 9 percent. OMG who the hell offers 9 percent are you kidding me. so to jasper transmission I am buying a trampoline so you can bounce up and kiss my ass.
